4a + 3 - 9 = -7 + 2 + a
4a - 6 = -5 + a
4a - a = -5 + 6
3a = 1 / : 3
a = 1/3

Answer:
8+2j like you say let j be the variable and more than means+
Total cost=$142
cost of parts=$62
cost paid for labour=$142-$62=$80
According to question,
》cost of labour per hr=$32
which can be written as,
》cost of labour/time=$32
Use cross multiplication,
》time=cost of labour/32
Since cost of labour is 80,
Time=80/32
=2.5hrs
Answer:
1. $8.
2. 48 counters.
Step-by-step explanation:
1. A pair of socks cost 20 - 2(6)
= $8.
2. let the number of counters in Box A and Box be be x.
Then the number of counters in Box B after the transfer is x + 1/2 x.
x + 1/2 x = 72
1.5 x = 72
x = 72 / 1.5
= 48.
